Answer and Step-by-step explanation:
The computation is shown below:
As we assume a and b are together and c and d are together
So, the equation would be
= 100ac + 10(ad + bc) + bd
Now another equation i s
= 100bd + 10(ad + bc) + ac
Now take both equations together
So,
100ac + 10(ad + bc) + bd = 100bd + 10(ad + bc) + ac
99ac = 99bd
ac = bd
Now Like here a = 2 b = 10 and c = 5 d = 1
So,
ac = bd = 10
So we can take an example like this
So, by considering the
And,
We can the same amount
So in the given question, the choices are not there so we can calculate by the above method
First, i would look at the word sum. what does it mean by sum? the sum of two numbers is what? I think of it as sum=its an addition problem and the sum is what those two numbers added together equal. For example the sum of one and two is thee.
Lets say Matt's number is x.
So we got three numbers here; x, 7.5 and 38.2.
how about i simplyfy; "the sum of his number and 7.5 is 38.2"
What it is saying is that...
x and 7.5's sum is 38.2
if sum means it is an addition problem and 38.2 is the answer to this addition problem between 7.5 and x, even though you want to find x... then if you know this, your neext step is to translate this into an equation.
x plus 7.5 equals 38.2
x+7.5=38.2.
when it is an equation, you must subtract 7.5 by both sides. so it would be x=38.2-7.5
38.2-7.5 is... 30.7
that means x, Matt's number, is 30.7.
to do some these kinds of problems, you have to translate the sentences into an equation.
when it says the word product it is a multiplication problem
when a number is decreased, it is less than the original amount. so you are subtracting from the original number. so it would be "the number minus lets say 2 is equal to lets say four." that would mean the number is 6. x-2=4 is the equation.
I hope this helped out... I don't have the time to explain everything... this info may help...
There is no common ratio or common difference. The first three terms increases more slowly than a cubic, but the last three increase more quickly than the cube of n. The pattern is not obvious to me. When the sequence is cast in recursive terms, you get
... a[n] = (48/13)a[n-2] + (59/39)a[n-1] . . . . a[1] = 2, a[2] = 9
The next term using this rule is 174 34/39, not an integer.
The coefficients p and q for a[n-2] and a[n-1] can be found from
_____
Any sequence of 4 numbers can be matched by a polynomial of degree 3 or less. Here, a calculator's polynomial regression function tells us the rule could be
... a[n] = 4.5n³ -24.5n² +49n -27
Using this rule, the next two terms are 168 and 357.
Answer:
1/2.
Step-by-step explanation:
f(x) = (1/8)^x
when x = 1/3
f(x) = (1/8)^1/3
f(x) = ∛(1/8)
f(x) = 1 / ∛8
f(x) = 1/2.
